Rookie Robert Griffin III showed no ill effects of concussion he suffered against the Atlanta Falcons, throwing a touchdown pass and rushing for two scores, as the Washington Redskins notched their first home victory with a 38-26 triumph over the Minnesota Vikings Sunday at FedEx Field.

Griffin completed 17 of 22 throws for 182 yards and a touchdown and led Washington's rushing with 138 yards on 13 carries with two scores, including a 76-yard run in the fourth period that put the game away with three minutes left.

The victory improved the Redskins to 3-3, good for a second-place tie with the Philadelphia Eagles in the NFC East. The defeat ended the Vikings' three-game run and dropped them to 4-2, second behind the Chicago Bears (4-1) in the NFC North.

Running back Alfred Morris added 47 yards on 13 carries and a touchdown while fullback Darren Young was the recipient of Griffin's six-yard touchdown pass in the second period.

The Vikings were led by Christian Ponder, who completed 35 of 52 passes for 352 yards and two touchdowns but had two interceptions while Blair Walsh kept them in the game with four field goals.

Walsh opened the first quarter with three field goals from 20 and twice from 27 yards to give the Vikings a 9-0 advantage.

It was the Redskins turn to shine in the second period, with Kai Forbath drilling a 50-yard field goal, Morris rushing for a touchdown and Griffin connecting with Young for a score, giving Washington a 17-9 lead.

Griffin made it 24-9 in the third with a seven-yard scoring run but Walsh countered with a 37-yard field goal to make it 24-12 at the start of the final period.

The Redskins padded their lead to 31-12 when Madieu Williams intercepted Ponder's pass to Michael Jenkins and returned it for a 24-yard touchdown.

Ponder then got hot, throwing two straight touchdown passes to Jenkins and Kyle Rudolph to cut the lead to 31-26 before Griffin wrapped up the victory with a 76-yard run.

Meanwhile, league sources said the Vikings will play a home game at Wembley Stadium in London sometime in September next season. An announcement is expected during the NFL owners meetings in Chicago Tuesday.

According to sources, the league wants to see how this game with Minnesota works out before giving the team another home game in London in 2014 as part of the NFL's expanding International Series.

With the development, London will get to see the Jacksonville Jaguars host the San Francisco 49ers and the Vikings host an opponent to be determined.
